The Dornier Do335 all-weather heavy fighter was the fastest piston-engine aircraft produced by Germany in World War II, capable of producing a maximum speed in excess of 750 km/h. This book contains a great deal of little-known and previously unpublished material and dispels many myths about this aircraft, which has been the subject of frequent erroneous assessments over the years. The authors' detailed text and numerous photos cover the Do335's planned development in various forms as a heavily armed day fighter, a night fighter, reconnaissance machien, destroyer/heavy fighter, and a trainer.
